Abstract

The structures which are to be expected during the steady state directional growth of alloys in a simple ternary eutectic system are discussed and it is predicted that for a particular velocity and temperature gradient five different structural regions can be observed. The structural regions of a two component system may be explained using a stability analysis and a competitive growth criterion, and it is suggested that these ideas may be extended to a three component system. Additional models have been proposed for the growth of a planar front two phase eutectic and single phase dendrites in a three component system.
